FOLDING MECHANISM.

Specification of Letters Patent.

Patented Jan.'1'7, 1911.

To (it! whom it may concern: I

lie it known that I, Osou: Ronsnlv, a cit-i zen of the UnitedStatcspresiding at New Yo1'k,-cou1ity of New York, and State of New York,have invented certain new and useful Improvements in Folding Mechanisms,fully described and represented in the following specitiation and theaccompanying drawings, forming a part of the same.

This invention relates to certain improvements in folding mechanisms forhigh speed rotary web printing machines.

it is common in the art and in that class of machin'cs known as straightline machines to run a multiple width web after it leaves the printingcouples direct, that is, in a straight; line andwitholusidewisedeflection, to folding mechanisms of the longitunal type, thesemechanisms operating to produce tolds'in the webs which are parallelwith the run of the webs. As each of these folding mechanisms folds itsweb loiigitmlinally out of the path in which the web is traveling, .nodi'llicnlty exists in properly locating the folding mechzu'iismsadjoining each other, because there is plenty of rooi'n, owing to thepeculiar characteristics of the folders, to dispose the operatingmechanisms. When, however, it was desired to give the webs a fold whichis transverse to the path ill-which the webs are running it has beencustomary to use turner bars by which the webs were deflected .sidewisc,this conetruction' affording the necessary space for installing thefolding devices and their operating mechanisms. It; will be understoodthat the folding mechanisms for high speed web machines, andparticularly those which produce a transverse fold, must. be run at veryhigh speeds, and they must be very strongly and substantially built inorder to stand the strains set. up by the higlrspeeds at which they arerun. This neces; "ztcsheavyframing and operating;- parts, requiringconsiderable space which was afforded by deflecting the webs.Ilcretofore, therefore, the advantages incident to a straight line ordirect run of the webs have not; been obtained Where transverse fol dingmechanisms were employed.

This lliTYBIlt'lOIl has for its object to produce an improved foldingmechanism for producing transverse folds in webs which are being runside byjside, the folding device for each web being 1 o hicatcd that thewells may be run direct. that is, in a straight line. without sidewisedctlcct'ion.

With this and other objects in view. the inrcntion consists in certainco'mtructions, and in certain hurts, in lr 'o'ements and combinations aswill be lw-ivinaftcr toll described and then specil'a-ully pointed out.

Referring to the arcmnpanyin 'drawings----liignre 1 illustrates indiagrammatic side elevation a folding mechanism constructed inaccordance with the invention. Fig. 2 is a front elevation oftheconstruw tion illustrated in Fig. l.

c, cute two webs which arc adrailrcd side by sideunderneath a guide roll3.

et. and?) indicate two similar webs which guide roll 6.

Machines constructed in'mrcorda-nce with the invention will em ploytransrerse folding mechanisms, that. is. folding mechanisms which are toproduce 'tolds which are transverse to the run of the web. \Vhile theparticular construction of transverse folding mechanism employed may beraricd, in the construction illnst'atcd, tl'iefolding mecha nisms are ofthe. rotary type and there will be one setof such rotary foldingmechanisms for each of the webs which are advanced side by side. In theparticular construction illns tratcd two such rotary foldingIDQCl'ItIIilSIflS are employed, these folding mechanisms beingsuperposed. One of these folding mechanisms, ae'illustrated, comprises atucking cylinder 7 and a jaw cylinder 8, this form of trai'isversefolder being well-known in the art. The other folding mechanism illnst'ated comprises a tucking cylinder 9 and a jaw cylinder 10, thesecylinders being similar in character to those just described. Prior tobeing operated upon by the cylindcrs 7,8 and 9, it the webs should beseparated into sheets. in the particular construction illustratml. thisis eti'cct-cd by rotary cutting cylinders the cylinders operating inconnection with the folding cylii'idcrs T. 3 being marked 11, IL- and13, and the cylinders operating in connectionwith the fold ing cylinders9, 10 being marked 1-1-, and 16. In this cutting construction,thecylinders 11, 1-3 and 14, t5 operate to partially sever ,the web; thewebs being completely severed by the cylinders 13 us operating inReferrin to the drawin 's. l and Q 'in:ti-.

are advanced sideby ride underneath a the side frame 40. It will beobserved that lead the webs l 'and 2 directly into the foldconnectionwith the cylinders 12, 15.

- sheets from the cylinder 10 are directed by .rclation to the sidefra'n'les 35), 36 that the 'sc'ribed,it is possible to make the two setsof ,n'ndthe parts connected therewith, as strong This 1 double cuttingconstruction enables forwarding tapes 17, 18 to be employed, by whichthe webs formed may be positively advanced to the folding cylinders. Inthe particular construction illustrated, the sheets finally cut by thecylinders 12, 13, 15, 16 are advanced through guides 19, 20 to thecylinders 7 and 9 respectively, tapes 21 and 22 being employed inconnection with these cylinders to keep the sheets on the cylinders.

After the transverse folds have been effected in the webs l and 1, inthe particular construction shown, the sheets may be delivered in anysuitable manner. In the particular construction shown, the sheets fromthe transverse folding mechanism 7, 8 are directed by a guide 23 into atape pathway consisting of two sets of coacting tapes 24, and to arotary fly 25, which fly in turnde-. livers the sheets to a carrier 26of ordlnary construction. If desired, tapes 27 may be used to cooperatewith the cylinder 8 and the guide 23 in forwarding the sheets. The

means of a guide'28 to a pair of rolls 29 which in turn deliver thesheets to a fly 30, this fly depositing them on an ordinary carrier 31.Tapes, as 32, may be employed to cooperate with the cylinder -10 and theguides 28 in forwarding the sheets.

The folding mechanisms may be mounted and driven in any suitable manner.In niachines constructed in accordance with the invention, thetransverse folding mechanisms whatever be their' construction Ewill besuperposed and will be so located tha the webs may be led direct, thatis, without sidewise dt fiection, to the mechanisms. In the machineillustrated, the folding cylinders 9, 10 are mounted on shafts 33,34:,gthese shafts being supported in side frames 35, 36. The cylinders7, 8 are, in the particular machine illustrated, mounted on shafts 37,38, these shafts being-supported in side frames 39, 40. These sideframes 89, I0 are, in the particular machine shown, carried on crossbars 41 which are supported in part on the side frames 35, 3G, and inpart by a frame 42 which, as shown, may be a continuation of the sideframes 39, a0 are so disposed with folding cylinders 7, S and the partsconnected therewith are offset with respect to the folding cylinders 9,l0 and the parts connected tl'iere 'vith. By superposing the foldingme'chanisms'andarranging them as defoldingmechanisms, their shafts andframes,

as may be necessary and at the same time to -1ng mechanisms, that is,without deflecting them sidew-ise.

When, as in the particular construction illustrated, two sets of websare advanced in superposed paths, they are conveniently handled anddirected to the folding mechanisms in the same manner as if a single setof webs were employed. In that case, the right hand halves of the websmarked 1 and 4- can be-led directly through the cutting cylinders intothe folding mechanisms, the webs being associated, in the particularconstruction illustrated before they reach the cutting cylinders. In'the same way, the left hand webs 2, 5 are led direct to the cylinder 9,10, the webs being associated beare advanced side by side underneath athese cylinders.

The driving mechanism for the folders may be of any suitable character.In the construction shown, the main shaft is illustrated at 40, thisshaft carrying a miter gear 44 which meshes with a cylinder 45 on acountershaft 4:6. This shaft carries a driving gear e7 from which,through suitable gearing, the various devices which constitute the lowerfolding mechanism may be driven. The shaft 46 also carries anotherdriving gear 48 which, in the machine shown, through a suitablevertically arranged train of gears, drives the upper folding mechanism.The construction illustrated further lends itself readily to theoperation of either folding mechanism independently in case it bedesired. By forming the gear 47 so that it may he slid on its shaft andconnecting its hub to the shaft.

in any suitable manner, as by a set screw 49, the operations, of thelower folding mechanism are interrupted. Similarly, by arranging one ofthe train of gears which drives the upper folding mechanism, as-forinstance, the gear marked 50, which is the gear which meshes directlywith the gear &5, so as to slide on its support or stud 51, theoperation of the upper folding mechanism may be interrupts It will beunderstood that suitable web guides not necessary to describe will beused where necessary in order to properly control the webs.

Changes and variations may be made in the construction by which theinvention is carried into effect. The invention is not, therefore, to belimited to the specific constructions hereinbefore described andillustrated in the accompanying drawings.

What is claimed is 1. The combination with means for advancing aplurality of unfolded webs side by side, of a plurality f superposedfolding mechanisms operating to produce foldstransversely to the run ofthe webs, and guides whereby said webs may be led direct to the foldingmechanisms.

2. The'combination with means for ad vancing a plurality of unfolded.webs side Webs running side by side, of two superposed foldingmechanisms operating to produce folds transversely to the run of theWebs, means for leading the right hand web of each set direct to one ofthe foldingmeehanisms, and means for leading the left hand web of eachset direct to the other folding 15 mechanisms. I

In testimony whereof, I have hereunto set my hand, in the presence oftwo subscribing witnesses.
